Closed Cell Spray Foam
Closed cell spray foam insulation is much denser than open cell. It has a smaller, more compact cell structure. It is a superb air barrier as well as a water vapor barrier by creating an envelope within the building. It is commonly used on roofs, sheds, agricultural, boats, containers all metal structures and other outdoor applications.
It also is a ridged yet flexible material which will not disintegrate over time producing harmful irritating particles into the air as do fiberglass and some other insulating materials. In the United States, after a 1994 report, Health and Human Services finally determined that fiberglass should be listed as a substance for which there is evidence of carcinogenicity in humans.
Container Insulation
Spray foam insulation is by far the best method used in the insulation of shipping containers. When insulating your shipping containers there are many benefits of choosing sprayed foam. Spray foam insulation not only prevents heat loss, it also regulates the cold temperatures too. The airtight seal of spray foam is ideal for maintaining the overall airflow inside the container whilst also keeping it perfectly watertight to prevent moisture build up and the formation of condensation on the interior walls.
